MISSION, Texas -- A kidnapping assault and assault investigation in Texas led authorities to the home of a U.S. Customs and Border Protection agent who was found dead inside.

The San Antonio Express-News reports Border Patrol agents found an injured woman Wednesday night. She claimed a man attacked her and two teenage girls. Agents found one of the girls nearby. She had been stabbed.

The suspect was determined to be one of their own agents. The investigation led to a home in Mission Thursday. The third victim was found inside and the agent, who authorities determine committed suicide.

The agent allegedly raped the victims too.

Several sources, including The Associated Press, identify the agent as Esteban Manzanares. A Border Patrol spokesman told the AP Manzanares had been with the agency since 2008 but did not elaborate on the kidnappings.

The victims are believed to be Honduran and were in the country illegally, law enforcement told the San Antonio Express-News.

A CBP official told the AP Manzanares was on duty when he encountered the females. His shift was over when authorities showed up at his home.
